C# 通过模拟http请求来调用soap、wsdl

 

C#调用webservice的方法很多，我说的这种通过http请求模拟来调用的方式是为了解决C#调用java的远程API出现各种不兼容问题。

由于远程API不在我们的控制下，我们只能修改本地的调用代码来适应远程API。

在以上情况下，我们就通过模拟http请求来去调用webservice。

 

首先，我们要分析调用端口时，我们发送出去的数据。

先抓个包看看，这里，我们没有办法用Fiddler来监听SOAP协议的内容，但是SOAP还是基于http协议的。

用更底层的工具是能够抓到的。这里可以去百度一下，工具很多。

不过我找了一个java写的，监听SOAP协议的小工具。《戳我下载》http://download.csdn.net/detail/a406502972/9460758

抓到包了之后，直接post就行了，简单易懂，直接上代码：

 1         static string data = @"发送的内容";
 2         private static string contentType = "text/xml; charset=UTF-8";
 3         private static string accept = "image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/x-shockwave-flash, application/x-silverlight, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, application/x-ms-application, application/x-ms-xbap, application/vnd.ms-xpsdocument, application/xaml+xml, application/x-silverlight-2-b1, */*";
 4         private static string userAgent = "Axis2";
 5         /// <summary>
 6         /// 提交数据
 7         /// </summary>
 8         /// <param name="url"></param>
 9         /// <param name="cookie"></param>
10         /// <param name="param"></param>
11         /// <returns></returns>
12         public static string PostWebContent(string url, CookieContainer cookie, string param) {
13             byte[] bs = Encoding.ASCII.GetBytes(param);
14             var httpWebRequest = (HttpWebRequest)WebRequest.Create(url);
15             httpWebRequest.CookieContainer = cookie;
16             httpWebRequest.ContentType = contentType;
17             httpWebRequest.Accept = accept;
18             httpWebRequest.UserAgent = userAgent;
19             httpWebRequest.Method = "POST";
20             httpWebRequest.ContentLength = bs.Length;
21             using (Stream reqStream = httpWebRequest.GetRequestStream()) {
22                 reqStream.Write(bs, 0, bs.Length);
23             }
24             var httpWebResponse = (HttpWebResponse)httpWebRequest.GetResponse();
25             Stream responseStream = httpWebResponse.GetResponseStream();
26             string html = "";
27             if (responseStream != null) {
28                 StreamReader streamReader = new StreamReader(responseStream, Encoding.UTF8);
29                 html = streamReader.ReadToEnd();
30                 streamReader.Close();
31                 responseStream.Close();
32                 httpWebRequest.Abort();
33                 httpWebResponse.Close();
34             }
35             return html;
36         }
